DropWise manufactures a “grafted” hydrophobic coating that, when applied to condenser surfaces in power plants, prevents water from building up on pipes and slowing down the condensation process. The coating, which causes water droplets to quickly bead up and shed themselves from a surface, is one two-thousandth the thickness of a sheet of paper so that it itself doesn’t block condensation, but it is also strong enough to survive years of steam exposure. In addition to inventing the coating, the team has also developed a novel approach for scaling up the manufacturing process to an industrial level and enabling the coating to stick to surfaces through strong chemical bonds.

The DropWise team expects that the new technology can save 0.58 gigatons of carbon dioxide emissions through improved efficiency — more than either solar or wind power. Watch how it works in the video below.
